Title: Actuator for water closet flushing cistern - has lever system for preventing excessive use of water
Inventor: REINHOLD GOTTWILL
IPC: E03D1/14
Filed: 1974-03-16
Abstract: The actuating system is used for draining the flushing cistern content of a water closet to a required arbitrary extent. In conventional flushing boxes the whole box contents is drained and this results in waste of water. Partial draining is achieved by lifting the draining valve plate into a position below the equilibrium floating position. In this case less water is drained and the valve plate is returned automatically when the handle is released. The lever system prevents raising of the valve plate above the floating equilibrium level. The lever system actuated by the projecting push buttons actuates a vertical valve stem. This stem has vertical slots at its upper end and through these slots passes the inner end of a pivoted first lever whose outer end forms a push button. This lever is used for complete draining of the cistern contents. The inner free end of this lever slides within vertical slot in the bracket at the end of another pivoted lever with a push button. The bracket movement is stopped by the lid. The second lever is used for draining smaller quantities of water. Repeated actuation of the second lever drains further quantities of water.
